经牙槽嵴顶入路的上颌窦提升植骨及同期种植体植入术

Maxillary sinus lifting and simultaneously placement of implants from the top of alveoli

目的 减轻传统的上颌窦提升术给患者增加的手术创伤 ,简化上颌窦提升牙种植的手术步骤。方法 应用Frialit 2骨挤压器对 1 1例患者 (1 4个牙位 )行经牙槽嵴顶入路的上颌窦提升、植骨即刻牙种植术 ,术后随访时间平均 1 5个月 (1 0～ 2 1个月 )。结果 1 1例 (1 4颗种植体 )未发现鼻出血、上颌窦炎症反应及种植体松动、脱落 ,X线检查种植体周围无阴影 ,已形成良好的骨结合。结论 应用Frialit 2骨挤压器行经牙槽嵴顶入路的上颌窦提升牙种植术是一种创伤小、操作简单。

Objective To study the effect of maxillary sinus floor elevation by the Frialit 2 Bone Condenser for implantation. Methods 11 patients underwent sinus floor lift by The Frialit 2 Bone Condenser and were inserted 14 implants The time of following up was 10 21 months Results There were no implant loose or lost, no clinical complaint of maxillary sinus area, and X ray exam showed well osseointegration Conclusions The Frialit 2 bone condenser can be used for lifting sinus floor, and the sinus elevation without lateral access allows the insertion of implants with no additionl surgical stress for the patients
